CLOSURE DEVICES FOR ALL AGES AND MOST PDA SHAPES AND SIZES.

Designed for flexibility, our innovative duct occluder options conform to a variety of ducts while achieving complete patent ductus arteriosus (PDA) closure from a pulmonary or aortic approach.

PATENT DUCTUS ARTERIOSUS (PDA)

Patent ductus arteriosus (PDA) happens when the ductus arteriosus, the arterial shunt in fetal life, fails to close after birth. The ductus arteriosus typically closes shortly after birth, creating the flow of blood directly from the heart to the lungs. If the ductus arteriosus doesn’t close, it creates a reverse blood flow from the aorta into the pulmonary artery and is then recirculated through the lungs. A medium to large PDA may require closure to avoid serious complications.

AMPLATZER PICCOLO™ OCCLUDER

The Amplatzer Piccolo™ Occluder, which delivers proven PDA closure for patients 700g and up, provides the strength to occlude small ducts while minimizing protusion into surrounding pulmonary artery and descending aorta.

  • Self-expanding device designed for closure of a patient ductus arteriosus
  • Low-profile retention discs and end screw engineered to minimizes protrusion into the aorta and pulmonary artery
  • Symmetrical design offers procedural flexibility to choose an aortic or pulmonary artery deployment approach
  • Device can be easily recaptured and redeployed for optimal placement
  • Tightly woven, single-layer mesh design to minimize residual shunt after placement
  • Flexible delivery cable optimizes deployment and allows for representative preview of device orientation prior to release

MR CONDITIONAL

St. Jude Medical’s AMPLATZER™ Duct Occluder II device is manufactured of chemically etched nitinol wire, 80% platinum 20% iridium marker band and a 316L end screw.
Non-clinical testing has demonstrated that the AMPLATZER™ Duct Occluder II device is MR-Conditional. Patients can be scanned safely immediately after implantation under the following conditions:

  • Static magnetic field of 1.5 Tesla (1.5T) or 3.0 Tesla (3.0T).
  • Maximum spatial gradient field less than or equal to 30 T/m.
  • Maximum whole-body-averaged specific absorption rate (SAR) of 2.0 W/kg (normal operating mode) for 15 minutes of scanning.

In non-clinical testing with body coil excitation, the AMPLATZER™ Duct Occluder II device produced a differential temperature rise of less than or equal to 3.65°C when exposed to a maximum average whole body specific absorption rate (SAR) of 3.35 W/kg for 15 minutes of scanning in a 3.0 Tesla MR system (Siemens™ MAGNETOM Espree™, SYNGO™ MR B17 software, Erlangen, Germany). Scaling of the SAR and observed heating indicates that average whole body SAR of 2.0 W/kg would be expected to yield a localized temperature rise of less than or equal to approximately 1.0°C in Normal Operating Mode.

In non-clinical testing with body coil excitation, the AMPLATZER™ Duct Occluder II device produced a differential temperature rise of less than or equal to 1.91°C when exposed to a maximum average whole body specific absorption rate (SAR) of 2.80 W/kg for 15 minutes of scanning in a 1.5 Tesla MR system (Siemens™ MAGNETOM Espree™, SYNGO™ MR B17 software, Erlangen, Germany). Scaling of the SAR and observed heating indicates that average whole body SAR of 2.0 W/kg would be expected to yield a localized temperature rise of less than or equal to approximately 1.0°C in Normal Operating Mode.

MR Image quality may be compromised if the area of interest is the same or relatively close to the
position of the device. Therefore, it may be necessary to optimize the MR imaging parameters for the presence of this implant.

POTENTIAL ADVERSE EVENTS

Potential adverse events that may occur during or after a procedure using this device may include,
but are not limited to:

Air embolus; Allergic dye reaction; Allergic drug reaction; Anesthesia reactions; Apnea; Arrhythmia; Bacterial endocarditis; Bleeding; Cardiac perforation; Cardiac tamponade; Chest pain; Device embolization; Device erosion; Death; Fever; Headache/migraine; Hypertension; Hypotension; Myocardial infarction; Palpitations; Pericardial effusion; Pericarditis; Peripheral embolism; Pleural effusion; Pulmonary embolism; Reintervention for device removal; Stroke; Transient ischemic attack; Thrombus; Valvular regurgitation; Vascular access site injury; and Vessel perforation.

Procedural

  • This device contains nickel-titanium alloy, which is generally considered safe. However, in vitro testing has demonstrated that nickel is released from this device for a minimum of 60 days. Patients who are allergic to nickel may have an allergic reaction to this device, especially those with a history of metal allergies. Certain allergic reactions can be serious; patients should be instructed to seek medical assistance immediately if they suspect they are experiencing an allergic reaction. Symptoms may include difficulty in breathing or swelling of the face or throat. While data is currently limited, it is possible that some patients may develop an allergy to nickel if this device is implanted. Some forms of nickel have also been associated with carcinogenicity (ability to cause cancer) in animal models. In humans, carcinogenicity has been demonstrated only through an inhalation route (breathing nickel in) which will not occur with this procedure.
  • The physician should exercise clinical judgment in situations that involve the use of anticoagulants or antiplatelet drugs before, during, and/or after the use of this device.

Post-implant

  • Endocarditis prophylaxis is carried out for 6 months according to the recommendation of the American Heart Association. The decision to continue endocarditis prophylaxis beyond 6 months is at the discretion of the physician.
  • Any patient who has a residual shunt will undergo an echo cardiographic evaluation of the residual shunt until complete closure of the defect has been confirmed.
  • Lung perfusion scan should be completed if flow through is greater than 3 m/s, or if the Z-score is -2 for the left pulmonary artery diameter.
  • MR Conditional to 3.0 Tesla
    Through nonclinical testing, the AMPLATZER™ device has been known to be MR Conditional at field strengths of 3.0 tesla or less with a maximum whole-body-averaged specific absorption rate (SAR) of 3.83 W/kg at 1.5 tesla and 5.57 W/kg at 5.0 tesla for a 20-minute exposure to a B1 of 118μ tesla. The AMPLATZER™ device should not migrate in this MR environment. Nonclinical testing has not been performed to rule out the possibility of migration at field strengths higher than 3.0 tesla.
    In this testing, the device produced a temperature rise of 1.1°C at 1.5 tesla and 1.6°C at 5.0 tesla.
    MR image quality may be compromised if the area of interest is in the exact same area or relatively close to the position of the device.
